Abstract
Recent advances in the understanding of the complex biology of non-small cell lung carcinoma (NSCLC), particularly activation of oncogenes by mutation, translocation and amplification, have provided new treatment targets for this disease, and allowed the identification of subsets of NSCLC tumors, mostly with adenocarcinoma histology, having unique molecular profiles that can predict response to targeted therapy. The identification of specific genetic and molecular targetable abnormalities using tumor tissue and cytology specimens followed by the administration of a specific inhibitor to the target, are the basis of personalized lung cancer treatment. In this new paradigm, the role of a precise pathology diagnosis of lung cancer and the proper handling of tissue and cytology samples for molecular testing is becoming increasingly important. These changes have posed multiple new challenges for pathologists to adequately integrate routine histopathology analysis and molecular testing into the clinical pathology practice for tumor diagnosis and subsequent selection of the most appropriate therapy.
